A New York jury found a hedge fund manager guilty of insider trading Wednesday in a trial involving former Dell Inc. employees.

Michael Steinberg, a former assistant to SAC Capital Advisors founder, was found guilty of five counts of conspiracy and securities fraud after one day of deliberations. Federal prosecutors alleged that Steinberg knew information related to Dell and Nvidia Corp. received from SAC Capital analyst Jon Horvath was improperly sourced. The trades Steinberg made using the information generated $1.4 million for him.

The 12-person jury began deliberations after the four-week trial in which it was alleged that two former Dell workers fed the hedge fund inside information.

Round Rock-based Dell, the No. 3 computer maker in the world, employs 14,000 workers in Central Texas. In 2007, Rob Ray, an employee in the company’s investor relations department, began feeding tips to a former Dell colleague-turned-Wall Street analyst who passed them on to SAC Capital.

Ray departed Dell in April 2010 and the company cooperated with the Department of Justice’s investigation, company officials said.

Steinberg was the first employee of SAC Capital to face trial in the long-running investigation of the hedge fund that resulted in its $1.2 billion plea deal last month.
